Definitions
- the present invention relates to a method of improving the growth and/or the yield of plants grown on agriculturally or horticulturally utilized substrates by applying at least one active compound (nitrification inhibitor) on agriculturally or horticulturally utilized substrates, wherein the at least one active compound I is added to the irrigation system in a water-dissolved form.
- Nitrogen is an essential element for plant growth, plant health and reproduction. About 5% of the plant available nitrogen in soils (ammonium and nitrate) originate from decomposition processes (mineralization) of organic nitrogen compounds such as humus, plant and animal residues and organic fertilizers. Approximately 5% derive from rainfall. On a global basis, the biggest part (90%), however, are supplied to the plant by organic and inorganic nitrogen fertilizers.
- the mainly used inorganic nitrogen fertilizers comprise urea and/or ammonium compounds or derivatives thereof, i.e. nearly 90% of the nitrogen fertilizers applied worldwide is in the urea and/or Nf form (Subbarao et al., 2012, Advances in Agronomy, 1 14, 249-302).
- Nf is held electrostatically by the negatively charged clay surfaces and functional groups of soil organic matter. This binding is strong enough to limit NfV-loss by leaching to groundwater.
- NO 3 ⁇ being negatively charged, does not bind to the soil and is liable to be leached out of the plants' root zone.
- nitrate may be lost by denitrification which is the microbiological conversion of nitrate and nitrite (NO 2 ) to gaseous forms of nitrogen such as nitrous oxide (N 2 O) and molecular nitrogen (N 2 ).
- ammonium (NH4 + ) compounds are converted by soil microorganisms to nitrates (NO 3 ) in a relatively short time in a process known as nitrification.
- the nitrification is carried out primarily by two groups of chemolithotrophic bacteria, ammonia-oxidizing bacteria (AOB) of the genus Nitrosomonas and Nitrobacter, which are ubiquitous component of soil bacteria populations.
- AOB ammonia-oxidizing bacteria
- Nitrosomonas Nitrosomonas
- Nitrobacter which are ubiquitous component of soil bacteria populations.
- the enzyme which is essentially responsible for nitrification is ammonia
- AMO monooxygenase
- the nitrification process typically leads to nitrogen losses and environmental pollution. As a result of the various losses, approximately 50% of the applied nitrogen fertilizers is lost during the year following fertilizer addition (see Nelson and Huber; Nitrification inhibitors for corn production (2001 ), National Corn Handbook, Iowa State University).
- nitrification inhibitors include biological nitrification inhibitors (BN Is) such as linoleic acid, alpha-linolenic acid, methyl p-coumarate, methyl ferulate, MHPP, Karanjin, brachialacton or the p-benzoquinone sorgoleone (Subbarao et al., 2012, Advances in Agronomy, 114, 249-302).

- the soil contained 73 % by weight of sand, 24 % of silt and 3 % of loam and had a pH of 6.8, a maximum water holding capacity of 25 % by weight and a C t value of 0.7 corresponding to 1.2 % by weight of humus.
- DM PSA provides for longer and stronger inhibition of nitrification in drip irrigation compared to DCD and Nitrapyrin.
- the results also show that DMPSA is almost twice effective as DMPP and thus only half amount of DMPSA is required to achieve comparable nitrification inhibition.
